Git Bash for loop through files - bash

Question

Okay, I am trying to loop through all images in a directory and do some compression on them. Here is my code.
#!/bin/bash
for f in *.jpeg; do
echo "Processing $f file..";
magick convert -quality 85% $f $f
done
And here is the output from it:
$ bash compress.sh Processing *.jpeg file.. convert: unable to open
image '*.jpeg': Invalid argument # error/blob.c/OpenBlob/3094.
convert: no images defined `*.jpeg' #
error/convert.c/ConvertImageCommand/3254.
The $f reference is actually the string "*.jpeg", which is definitely not correct.
Here is my folder structure.

Answer 1

I ended up doing this, which does the job.
#!/bin/bash
find ./images -name '*.jpg' | while read FILE; do
magick convert -quality 75% "$FILE" "$FILE"
done

You should lookup files with appropriate filename mask (directory and extension). Also there should be skip path if bash can't expand filename:
#!/bin/bash
IMAGE_PATH=`dirname ${BASH_SOURCE[0]}`/nature
for f in $IMAGE_PATH/*.jpg $IMAGE_PATH/*.jpeg; do
echo -n "Processing $f file... ";
if [ ! -r "$f" ]; then
echo "skip!";
continue;
fi;
magick convert -quality 85% "$f" "$f";
echo "done.";
done
PS: "$f" (with quotes) used for files with spaces in their names.
UPDATE: Add using script directory.
